This easy keto fudge with cocoa powder is chewy, chocolatey and perfectly sweet, even though it is made without any sugar. Even better, each piece has 0 net carbs.
I made a batch of my Keto Chocolate Peanut Butter Fudge last week. It is delicious and I have been eating a square every day.
But every time I wondered: Why have I never tried making a chocolate fudge without peanut butter?
After all, I have a dedicated keto peanut butter fudge recipe, but no classic fudge!
Without further ado, I went into recipe creation mode. And here is the result: the creamiest, richest and most decadent keto chocolate fudge you can imagine.
I made the recipe four times until I arrived at the perfect ratio of ingredients. I know exactly what works - and what does not work. I learned the hard way!
In this post, I will show you how to make smooth and fail-safe sugar-free fudge with cocoa powder and sugar-free condensed milk.
It tastes just like authentic chocolate fudge. You won't believe how chewy and yummy it is.
🌟 Why You'll Love This Recipe
- Creamy, chewy fudge texture
- Deep chocolate flavor
- Naturally gluten-free
- Sugar-free and keto friendly
- Only 5 ingredients and 0.8g net carbs per square
Here are the ingredients you'll need:
- Heavy Cream - This is also called heavy whipping cream or double cream.
- Butter - I used salted butter for additional flavour. Unsalted butter is also an option.
- Allulose - This is the best sweeter for this fudge recipe because it does not recrystallise like other zero-carb sugar substitutes. Allulose melts just like sugar.
- Unsweetened Cocoa Powder
- Vanilla Extract - Optional, but it does improve the flavour.

It's surprisingly easy to make this keto chocolate fudge recipe. Here are the basic steps.
For detailed instructions, scroll down to the recipe card.
Step 1: First, make the keto condensed milk. Put the heavy cream, butter, allulose and vanilla extract into a saucepan. Bring the mixture to a boil over medium heat.
Step 2: Simmer the mixture over medium to low heat for 20 minutes until golden and thickened. Stir regularly. Towards the end, stir continuously.
Step 3: Turn off the heat and stir in the unsweetened cocoa powder.
Step 4: Pour the fudge mixture into a dish that you have lined with parchment paper.
Put the fudge in the freezer until it has fully set. Then, cut it into 16 squares with a sharp knife.
Stir the condensed milk regularly while it is cooking on the stovetop. Towards the end of cooking, stir it continuously. This way, it can thicken as much as possible and does not burn.
Allulose really is the best sweetener for this recipe, because it sets so smooth. I first used it in my chewy keto toffee.
Warm the knife blade before cutting and clean the knife between cuts.
Dairy-free option: It is easy to make a dairy-free sugar free fudge. Simply replace the cream with coconut cream and use coconut oil instead of the butter.
Another idea is to omit the cocoa powder and make a classic butter fudge. For this, add an additional tablespoon of butter. Also, cook the condensed milk for a further 5 minutes until it turns into a darker caramel.
Or how about peppermint chocolate fudge? Add ½ teaspoon mint extract to the mixture.
Last but not least, you could add a keto caramel swirl to the fudge.
I topped my keto fudge with coarse sea salt flakes. Here are other ideas for toppings:
- Chopped nuts. Chopped pecans are my favourite option. Walnuts, almonds or hazelnuts also work. Toasting the nuts first increases their flavour.
- Unsweetened desiccated coconut or toasted coconut flakes.
- Freeze-dried raspberries or sugar free dried cranberries
- Grated orange zest
Sugar-free fudge is very low in carbs. One square of this chocolate fudge contains only 0.8g net carbs.
I recommend allulose. It is the only zero-carb sugar substitute that sets smooth and does not re-crystallise as it cools.
Yes. You can use erythritol or erythritol monk fruit sweetener blends such as Lakanto. Bocha Sweet, Swerve or xylitol will also work. It is very important to use a powdered sweetener. Granulated sweeteners will give the fudge a gritty texture. Also, if you are not using allulose, reduce the sweetener amount by 1 tablespoon.
I don't recommend it because sugar free chocolate seizes easily when heated. This causes the fudge to separate. After two failed attempts, I made one successful fudge version using sugar-free chocolate chips instead of cocoa powder. I found that once the melted chocolate is added, the mixture firms up very quickly. It was not as smooth as the version with cocoa powder.
No, the recipe is not suitable for the microwave.
Store keto chocolate fudge in an airtight container in the fridge for up to 1 week. Or, store it in the freezer for up to 3 months. I think it tastes best straight from the freezer.
Keto chocolate fudge is also a delicious mini dessert.
